Companies have come to rely on cookies to gather consumer data and serve targeted ads online. But fewer than 50% of consumers accept cookies, and data privacy laws are being codified around the world. Add to that growing consumer expectation of privacy coupled with shrinking marketing budgets—it all adds up to a whole new era for advertisers. And just like any new era, this calls for new technologies. Television New Zealand (TVNZ), New Zealand’s state-owned, partnered with Slalom and AWS to enhance personalized advertising on its streaming app, TVNZ+, while maintaining consumer privacy, integrating a new AWS capability called AWS Clean Rooms. Now TVNZ can collaborate with leading brands and agencies to unlock customer data and serve targeted ads to increase return on ad spend (RoAS) as much as 10x while respecting consumer privacy.
